Recently, some studies investigated hydrodynamic behaviour inside emitter channel by suing the CFD method [9, 10, 11].
Simulation results The simulations of the four types of drip emitters (table I) by adopting the three chosen models have been conducted.
The curves indicate that there is a good agreement between the results of the three models and the simulated results of CFD simulations.
However, these factors have not been taken account in the simulations.
